MECHANISM FOR PULLING: POTATO-HALIVIS.

SPECIFICATION forming part of Letters Patent No. 764,655, dated July 12,1904.

Application filed August 13, 1903. Serial No. 169,369. (No model.)

1'0 (LU whom it may concern:

Be it known that I, MARoUs AL'rsTooK, a subject of the Emperor ofAustria-Hungary, residing at 13 Kazimirgasse, Lemberg,'Galicia,Austria-l-Iungary, have invented a new and useful Improvement inMechanism for Pulling Potato-Halms, of which the following is aspecification.

This invention relates more particularly to mechanism for pullingpotato-halms, and the pulling devices are preferably operated from therear wheels of the machine, the arrangement being such that the halmsare thrown off laterally onto a row from which the potatoes have beendug.

This invention is shown in the accompanying drawings, in which Figure lis a plan view of the machine embodying this invention. Fig. 2 is a sideelevation of the pulling mechanism. Fig. 3 is a cross-section of thepulling-cylinders and also shows a second position of said cylinders indotted lines. Fig. 4 is a view showing a detail of construction.

The pulling mechanism consists of two rollers or cylinders 1, which areflattened on both sides and pointed at the forward ends. The cylindersare carried by shafts having their bearings in yielding arms 12. Theyare revolved in opposite directions to pull the halms, which aredirected between them by means of cone-gears 9, which drive one of theshafts upon which said cylinders are mounted, and intcrmeshing gears 10,mounted on said shafts. One of the cone-gears is driven by asprocketwhecl I, which is connected, by means of a chain andcorresponding sprocket-wheel, to a main shaft 5, which is in turn drivenby means of spocket-wh-eels 3 3 and chain from the rear axle 2.

Plates or shoes 7 immediately beneath the cylinders are provided withlugs or fingers 6, which direct the halms into the space between theconical or pointed ends of the cylinders, the plate 7 preventing earthor potatoes from being thrown up with the halms. A guide-plate 8, havingthe form of a reversed plowshare,

is provided adjacent to the upper surfaces of the cylinders, upon whichthe pulled halms fall and by means of which they are thrown offlaterally onto a row which has already been operated upon.

It will be observed that in starting in a field the first two rows mustbe pulled before the machine is used.

The cylinders or rollers 1 are covered with a layer of leather, rubber,or like material, and they may also be built up of thin plates, whichare connected by bolts, as shown in Fig. 3.

This pulling mechanism is preferably attached to one side of apotato-digging machine, as shown in the accompanying illustration; butit may also be used for other purposes and on other machines.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a machine'for pulling potato-halms, the combination of twocylinders which are flattened on both sides and terminating in forwardly-pointed ends, yielding arms upon which said cylinders aremounted, inter-meshing gears for driving said cylinders to cause them tocooperate for pulling the halms, and means for driving one of saidcylinders from the rear-wheels axle of the machine.

2. In a machine for pulling potato-halms, the combination of twocoacting cylinders flattened on both sides, coverings for said cylindersof suitable material, means for operating said cylinders, a slottedcatch-plate beneath said cylinders, provided with lugs for directing thehalms into the space between said cylinders, and a discharge-plateformed like a reversed plowshare for discharging the halmslaterally fromsaid cylinders.

In witness whereof I have hereunto signed my name, this 28th day ofJuly, 1903, in the presence of two subscribing witnesses.
